I know that cassettes have been a topic a number of times, but I am going to revisit it again. I realised yesterday that my Campy cassette on a set of my training wheels needs replacing. I was going to replace it with a Campy 10spd steel Chorus cassette, but at a $100 or more I might as well look into titanium. I know some people have used the Cycling Dynamics cassettes, but I do not see any 10spd listed on there web site. What is the best bet for a good long wearing cassette that doesn't cost a fortune and shifts as well as Campy cassettes?

Call cycle dynamics, they do all sorts of cassettes and do have a 10 speed

If you can find them, the Miche 10-speed cassette is an all steel campy compatible for a good price. I have on on my training bike and it's great, shifts perfect. They may be a bit hard to find .. I got a 12-25 for $40 at glorycycles.com but I don't think he carries them anymore. He might be getting some in drop them an email if that sounds interesting.
